Heya all, I don''t think I''ve been paying attention. When a Windows API function fails, I could have been doing this: raise SystemCallError(GetLastError()) Instead of this: # Where ''Error'' is nested under the current class. raise Error, get_last_error I''m not sure how big of a deal this is in practice, however, or if it''s even preferred for

Hi all, Looking at the IO.readlines source in io.c, it looks to me like they grab 8k chunks, split on the input record separator, and buffer accordingly. Since it looks like ReadFileScatter() does some of that work automatically (in page file sized chunks), I thought I''d give it a try. Here''s what I''ve got, but it doesn''t work. I have an incorrect parameter

Similar to python and perl. But MUCH easier (especially considering that this is the first time I've every tried to run Ruby). I even had fun making set_error() polymorphic.

Hi, I have one minor issue. I''m trying to check whether a directory is empty given some path to the directory. My code does the following: if(File.directory?(dirpath)) # dirpath = public/images/1 if(File.zero?(dirpath)) FileUtils.rm_rf(dirpath) end end The problem is, while testing this, if I put a file in the directory and run the above code, it still ends up deleting the

Hi, I have a problem where I need an auto-incremented id back from the database for a statement that has yet to be committed. The operation that uses the id may fail, and if so, I need to rollback the database. I can''t figure out how to send only the statement to the database without the commit without sending over hard coded SQL. This is what I started out with: 1 def add_album

Probably a simple question, but humor me: Let''s say I have a page (in Rails) that lets a user type a shell command (say, ''ping blah.com'') into a form and it fires off a worker that then updates that page using AJAX (all of this is working so far). How would I correctly wrap the worker in a begin..rescue so that it spits out ''invalid command''

Hi, I have a quick question. I am trying to create folders dinamically using FileUtils.mkdir, the problem is that if the folder already exist it gives me an error. Does anyone know if there are any options to mkdir that would let me overwrite the already existing directory? I just need to create a folder with the same name everytime. Any other solution you might suggest? Thanks. -- Posted
